Appearance starts in your cells. Three things come together here: building blocks for skin, hair and nails, support for cell renewal, and a raw material from the fastest-growing tissue in mammals.
Skin, hair and nails need constant renewal and proper nourishment. NOVA CELLCARE™ provides biotin, zinc and vitamin A, which help keep them in normal condition. Zinc is involved in cell division and protein synthesis, and hyaluronic acid is a natural component of skin that binds water.
What might you notice? If you have been low in these nutrients, topping them up may lead to a gradual improvement in the condition of your skin, hair and nails. Oral hyaluronic acid is also being studied for improving skin hydration and elasticity.
Four areas the formula supportsBiotin 2000 µg and zinc 15 mg. Biotin and zinc contribute to the maintenance of normal hair.
Zinc contributes to the maintenance of normal nails. Vitamin B6 contributes to normal synthesis of cysteine, an amino acid that makes up a large part of keratin.
Vitamin A, zinc and biotin contribute to the maintenance of normal skin. Plus 200 mg of hyaluronic acid and gotu kola.
Vitamin E and zinc contribute to the protection of cells from oxidative stress, the everyday burden that speeds up tissue wear.
Longevity isn’t just about the number of years you live; above all, it’s about your body’s ability to stay fit and functional as you age. Every day, billions of cells take part in renewal processes, use energy and switch on protective mechanisms. To work properly, they need an adequate supply of vitamins and minerals.
NOVA CELLCARE™ provides nutrients that support five biological processesEvery day, your body replaces worn-out cells with new ones. Zinc contributes to normal DNA synthesis and to the process of cell division, both essential for natural tissue renewal.
What does this mean for you?You support the basic biological processes that allow your body to maintain normal tissue structure and function.
Proteins have structural and enzymatic roles and take part in many processes inside cells. Zinc contributes to normal protein synthesis.
What does this mean for you?You give your body a nutrient it needs for normal protein production, which the function of your cells and tissues depends on.
Amino acids are used to build proteins and many other biological compounds. Vitamin B6 contributes to normal protein metabolism and is also involved in cysteine synthesis.
What does this mean for you?You support the proper use of the nutrients your body needs to function day to day.
Oxidative stress is one of the processes studied in the context of biological aging. Vitamin E and zinc contribute to the protection of cells from oxidative stress.
What does this mean for you?You support your cells’ natural protective mechanisms, which matter throughout life, including as you age.
Cells constantly need energy to do their work. Vitamin B1 supports normal energy-yielding metabolism, and vitamin B6 contributes to the reduction of tiredness and fatigue.
What does this mean for you?You support the normal processes of getting energy from food, as well as the metabolic functions you need for everyday activities.
Daily activity, work and a busy lifestyle demand efficient energy metabolism and a properly functioning nervous system. NOVA CELLCARE™ provides nutrients involved in these processes, helping your body use energy from food and maintain normal metabolic function.
Five areas of everyday supportVitamins B1 and B6 contribute to normal energy-yielding metabolism, the processes by which your body uses energy from food.
Vitamin B6 contributes to the reduction of tiredness and fatigue. An important function for anyone who wants to stay active day to day.
Vitamins B1 and B6 support the normal functioning of the nervous system, which helps coordinate your everyday activities and responses.
Zinc contributes to normal carbohydrate metabolism and metabolism of fatty acids, and vitamin B6 to normal protein and glycogen metabolism.

Each of us has a different reason to take care of ourselves. For some, it’s healthy-looking skin, hair and nails. For others, it’s mindful aging and caring for their body for years to come. Others still want to support their vitality in a busy everyday life.
NOVA CELLCARE™ was created for the most demanding. For people who invest in themselves consciously, expect well-thought-out solutions and accept no compromises in caring for their body every day. That’s why we combined 10 carefully selected active ingredients in one formula.

They think about health in terms of decades. They look after their cells, their natural protective mechanisms and mindful aging.

They juggle demanding work with everyday responsibilities. They want to support energy metabolism and reduce tiredness.

They train regularly and take conscious care of their bodies. They prioritize normal metabolism, a healthy look and long-term condition.
What can your body gain?
Skin, hair and nails run on their own biological clock. No supplement can speed it up, but what your body builds new tissue from depends on what you give it. That’s why consistency matters. Individual results may vary.
of the reference intake of biotin per daily serving (2000 µg).
Plus 15 mg of zinc, or 150% of the RI.
Step one: normal energy-yielding metabolism. Vitamins B1 and B6 are involved in turning nutrients into energy, and vitamin B6 contributes to the reduction of tiredness and fatigue.
Everyday life: You make regular supplementation part of a routine that supports an active lifestyle. Appearance: You provide the nutrients needed to maintain normal skin, hair and nails. Well-being: If you were previously low in B vitamins, you may gradually notice less weakness and tiredness.
Your skin is constantly renewing itself. The epidermis goes through natural renewal cycles, and vitamin A and zinc help maintain normal skin. Hyaluronic acid is also being studied for improving skin hydration.
Everyday life: Regular care for your skin becomes part of your habits. Appearance: You can start observing your skin’s condition, especially dryness and tightness, although improvement after one month is not guaranteed. Well-being: Greater skin comfort, if hydration really does improve, can have a positive effect on how you feel day to day.
Consistency lets you assess changes over a longer period. Biotin and zinc help maintain normal hair, and research on oral hyaluronic acid suggests that some skin parameters may improve after several weeks of use.
Everyday life: You can compare the condition of your skin and hair with how it was when you started. Appearance: Potential changes include better skin hydration and smoothness. Hair improvement is most likely if you were previously deficient. Well-being: Noticing positive changes can make your daily care routine more satisfying.
Long-term condition starts with regular habits. After 90 days, you have had three months of nutrients that support normal skin function, metabolism and the protection of cells from oxidative stress.
Everyday life: You have built a routine you can consciously continue. Appearance: This is a good moment to compare your skin hydration, hair and nails with how they were when you started. Changes may be subtle or unnoticeable. Well-being: You can assess whether you notice a difference in your daily functioning, especially if supplementation has helped correct earlier deficiencies.
Rare raw materials plus micronutrients with EU-authorized claims in one serving. A typical hair, skin and nails supplement is usually just biotin and zinc.

Test the formula for yourself
In its raw form, antler protein consists of large, hard-to-digest molecules. That’s why the capsule contains a hydrolysate, and the whole formula goes into a plant-based shell as pure powder.
Hydrolysis cuts the large proteins of red deer antler into shorter peptides and amino acids, which the body digests more easily than the unprocessed raw material.
Shorter molecules instead of raw protein.
A shell made of hydroxypropyl methylcellulose, a plant cellulose, with no gelatin. The formula does contain antler, however, so it is not vegan.
Plant-based shell, no additives.
The ingredients go into the capsule as powder, at the doses on the label, with no carriers, colorings or fillers.

Three mechanisms described in the scientific literature. Click point 01, 02 or 03 to see the diagram. Stay Demanding. Demand more from yourself, from the formula and from the brand.
Every day, your body makes new cells, synthesizes proteins and replaces worn-out structures. These processes are what allow your skin to keep its protective function, your hair to grow and your nails to gradually rebuild.1-3
For these processes to run normally, they need an adequate supply of nutrients such as zinc, biotin and vitamins A and B6.
5 mechanisms of natural renewal
Epidermis: continuous cell turnover
New cells form in the deeper layers of the epidermis, gradually move up to the surface and replace old ones. The whole process usually takes several weeks.
What’s in it for you? Normal renewal helps maintain the skin’s protective function, natural structure and healthy appearance. Vitamin A and zinc help maintain normal skin.
Hair: a continuous growth process
Cells in the hair follicles divide intensively and then produce keratin, which forms the hair shaft. Scalp hair grows by about 1 cm a month on average.
What’s in it for you? Normal hair follicle function is essential for maintaining healthy hair. Biotin and zinc help keep hair in normal condition.
Nails: steady rebuilding of the nail plate
New cells are constantly formed in the nail matrix; they fill with keratin and form the hard nail plate. Fingernails grow by about 3 mm a month on average.
What’s in it for you? Normal nail plate formation keeps nails healthy. Zinc helps maintain their normal condition and is involved in protein synthesis.
Collagen: skin structure and elasticity
Fibroblasts in the dermis produce collagen, which forms a network that gives tissues strength and support. With age, the balance between its production and breakdown shifts.
What’s in it for you? Collagen is responsible for the skin’s mechanical strength and firmness. Normal protein synthesis requires zinc, among other things, but taking zinc does not automatically mean more collagen is produced.
Keratin: the natural building block of hair and nails
Keratin is a structural protein rich in cysteine. The bonds between its molecules give hair and nails their characteristic strength.
What’s in it for you? Normal keratin formation is important for the structure of hair and nails. Vitamin B6 supports cysteine synthesis, and zinc supports normal protein synthesis.

Deer antler can grow by as much as 20 mm a day, almost 60 times faster than human hair. Every year, a deer sheds its antlers and then rebuilds them from scratch.4,5
Growth rate per day.
This exceptional process involves intensive cell division and the formation of new tissue, which is why antler is studied in research on natural regeneration mechanisms. Antler hydrolysate provides peptides and amino acids, but it has not been shown that supplementing it triggers similar regenerative processes in humans.
New every year
Antler is the only mammalian organ that regenerates completely, together with its bone, blood vessels and skin.
Stem cells
Growth is driven by cells from the periosteum at the base of the antler, which are studied in the context of tissue regeneration.
A raw material, not a drug
The hydrolysate is a source of peptides and amino acids. Human studies on its effects are still few.
What does this mean for you?NOVA CELLCARE™ provides an ingredient derived from a biologically exceptional tissue that is studied for its renewal mechanisms. It is an interesting element of the formula, although its effect on the regeneration of human tissue has not been clinically confirmed.

Less collagen, more oxidative stress and slower renewal. Some of these factors are within your control.2,3
1 · LESS COLLAGEN
After the age of 20, the skin’s collagen content falls by about 1% a year.
2 · OXIDATIVE STRESS
UV and pollution generate free radicals that damage skin fibers.
3 · SLOWER RENEWAL
With age, the epidermal turnover cycle gets longer.
4 · BUILDING BLOCKS
The zinc, biotin and vitamins your body needs to build new tissue come from your diet.

Reviews come from our store’s customers. Individual experiences may vary.
It's nice to find a product whose formula can actually be analyzed. My plus is the clear dosage for each ingredient. It looks good. The only downside is remembering to take two capsules consistently every day.
Without making claims about results, the listed 2,000 µg of biotin and the plant-based capsule shell deserve attention. These are verifiable product features.
The biggest plus for me is the 200 mg of hyaluronic acid. Specific and free from unnecessary marketing.
I try to avoid buying several separate products unnecessarily. The interesting part here is the transparent dosage information for every ingredient. I like that approach.
This doesn't replace a good diet or a sensible routine, but the formula itself makes sense to me. Two highlights are the ingredients designed to provide nutritional support for beauty care and Terminalia chebula. That's a reasonable starting point for...
